MeSU-beta is a SGI ICE-XA server (SGI presentation), which has the particularity of being a distributed cluster. It is made of 3012 high performance computing cores, distributed in 144 nodes of 24 cores, and is associated with a fast storage system based on a Lustre filesystem. MeSU-beta also has the particularity of being an extremly energy efficient server, and is equipped with a warm-water cooling distribution unit (CDU), capable of cooling up to 305 kW.
MeSU-alpha is equipped with 144 computes blades, each of which made of one motherboard (or node), equipped with two Intel Xeon (Sandy Bridge) of 12 cores each, and with a local memory of 128Gb. The nodes are connected by an Infiniband system, which allows for fast communication between them.
